MTN *****

On the evening of 22 February I was contacted by a person claiming to be from MTN. As he had access to all my information I did not suspect any *****. He stated that someone is trying to do a sim swop on my account and if I am aware of that. Obviously I was not. He stated that he will pass it through to their ***** dept. He stated that I will receive a sms with code from MTN and I must give it to him 5 minutes later, my spend limits was adjusted to R 12 499.00. I immediately phoned MTN, spoke to a lady, who's name I will not mention at this stage, stating that she will log the case and I must send certain documentation through with an Affidavit, and they will refund my money. I did as they asked. Still the money deducted from my account. I sent a number of emails asking for feedback, but just getting none. I am a MTN customer since 2000. My concern is that my information was accessed by ********** people. They have my new email address, all the numbers from all my MTN contracts ID number etc.. That really concerns me. So this morning I spoke to them again, submitted my documents for a third time. Received a sms that case are opened, 5 minutes later case closed???
